Home/ TIL the first PC virus was called "brain" and the hackers were not anonymous

Today I learned the first PC virus was called "brain" and was written in DOS only 25 years ago in 1986. The creators of the virus even gave their address. How did it move from PC to PC? Floppy disks of course. (The first Apple virus was called Elk Cloner and written a few years earlier by a 15-year old boy.)

Brain is the industry standard name for a computer virus that was released in its first form in September 1986[1], and is considered to be the first computer virus for MS-DOS. It infects the boot sector of storage media formatted with the DOS File Allocation Table (FAT) file system...

Welcome to the Dungeon (c) 1986 Brain & Amjads (pvt) Ltd VIRUS_SHOE RECORD V9.0 Dedicated to the dynamic memories of millions of viruses who are no longer with us today - Thanks GOODNESS!! BEWARE OF THE er..VIRUS : this program is catching program follows after these messages....$#@%$@!!

There are many minor and major variations to that version of the text. The virus slows down the floppy disk drive and makes seven kilobytes of memory unavailable to DOS. Brain was written by two brothers, Basit and Amjad Iqbal, who at the time lived in Chahmiran, near Lahore Railway Station, in Lahore, Pakistan. The brothers told TIME magazine they had written it to protect their medical software from piracy, and it was supposed to target copyright infringers only.[2] The cryptic message "Welcome to the Dungeon", a safeguard and reference to an early programming forum on Dungeon BBS, appeared after a year because the brothers licensed a beta version of the code...

The virus came complete with the brothers' address and three phone numbers, and a message that told the user that their machine was infected and to call them for inoculation:

The reason for this message is that the program was originally used to track a heart monitoring program for the IBM PC, and pirates were distributing bad copies of the disks. This tracking program was supposed to stop and track illegal copies of the disk. Another programmer copied the technique for DOS and it became the Brain virus. Unfortunately, the program also sometimes used the last 5k on an apple floppy, making additional saves to the disk by other programs impossible. The company was sued for damages and was quickly dissolved.

We all admire beauty, but the mind ultimately must be stimulated for maximum arousal. Longevity in relationships cannot occur without a meeting of the minds. And that is what Braincrave is: a dating venue where minds meet. Learn about the thoughts of your potential match on deeper topics... topics that spawn your own insights around what you think, the choices you make, and the actions you take.

We are a community of men and women who seek beauty and stimulation through our minds. We find ideas, education, and self-improvement sexy. We think intelligence is hot. But Braincrave is more than brains and I.Q. alone. We are curious. We have common sense. We value and offer wisdom. We experiment. We have great imaginations. We devour literacy. We are intellectually honest. We support and encourage each other to be better.

The Braincrave.com discussion group on Second Life was a twice-daily intellectual group discussions typically held at 12:00 PM SLT (PST) and 7:00 PM SLT. The discussions took place in Second Life group chat but are no longer formally scheduled or managed. The daily articles were used to encourage the discussions.
